House Sitting Background Checks 2026: What Each Platform Does

Home > Blog > House Sitting Background Checks 2026: What Each Platform Does

Background checks and ID verification are useful layers of reassurance in house sitting, but they are not the whole picture and they are not all created equal. Only one major platform runs a standardised criminal background check, and even that is limited to one country. Here is exactly what each platform does, what it actually means, and what experienced sitters and homeowners tend to rely on instead.

Caro and I have been house sitting for three years, on and off since Bochum in June 2023, and full-time since November 2025. Across 20 sits and 12 countries, we have completed verification checks on the platforms that require or offer them.

This article covers what each platform actually does, what those checks do and don't tell you, and where the real trust in house sitting tends to come from. If you're not yet on TrustedHouseSitters, a 25% discount on membership is available here.

What Background Checks and ID Checks Actually Are

These two terms get used interchangeably but they refer to different things, and the distinction matters.

An ID check confirms that a person is who they say they are. It cross-references personal details against public databases, government records, or document verification systems to confirm identity. It tells you that the name and document are genuine. It does not tell you anything about the person's history, reliability, or character.

A criminal background check goes further. It checks a person's criminal record and flags any history that might be relevant to trust and safety. It is a more meaningful layer of verification, but it is also significantly harder to run across international borders, which is why no platform currently runs it outside the US market.

The practical implication: when a platform says a sitter is "ID verified," it means their identity has been confirmed. It does not mean they have been vetted for character, reliability, or suitability as a house sitter. Those things come from somewhere else entirely, and we cover that at the end of this article.

TrustedHouseSitters: The Most Comprehensive Verification

TrustedHouseSitters is the only major house sitting platform with both mandatory ID verification for all sitters worldwide and a free criminal background check for US-based sitters. Both are handled through Evident, an accredited third-party provider.

ID verification is mandatory for all sitters as part of setting up a profile. It cannot be skipped. The check confirms identity by cross-referencing a passport, driving licence, or national identity card against databases that verify the document is valid and hasn't been reported as lost, stolen, or compromised.

The criminal background check is currently available to US-based sitters only. It is free and conducted through Evident. Once complete, it displays on the sitter's profile as a visible badge, which homeowners can see before selecting a sitter. Non-US sitters cannot currently access this check through the platform.

When Caro and I first signed up to TrustedHouseSitters, we both completed ID verification. THS later introduced a duo membership feature, which meant Caro's separate verification was absorbed into the shared account, removing her individual badge in the process. If you're in a couple using the platform, this is worth being aware of.

Our TrustedHouseSitters review and pricing guide cover the full platform in detail.

Aussie House Sitters, House Sitters America, Kiwi, Canada and UK: Optional Paid ID Check

These five platforms, all part of the same group of country-specific sites, offer an optional ID verification for a one-off fee of around $5 USD or the local equivalent.

The verification is not mandatory. It is a badge that can be added to a sitter's profile if they choose to pay for it. On Aussie House Sitters specifically, the check is run through Trulioo Global Gateway, an internationally recognised identity verification service. Sitters choose one document, an Australian driving licence, passport, Medicare card, or visa to enter Australia, and their details are cross-referenced against public databases to confirm identity. International sitters can use the visa option.

The badge appears on the sitter's profile once verified. It is a trust signal for homeowners browsing sitters, but it is entirely optional and many experienced, well-reviewed sitters don't have it. None of these platforms run criminal background checks. There is no equivalent to the THS US background check on any of these sites.

For Australia-based sits specifically, Aussie House Sitters remains a strong recommendation regardless of whether a sitter has completed the optional ID check. Our house sitting in Australia guide covers the full Australian platform landscape and how these platforms compare on listing volume.

HouseCarers: The Most Comprehensive Voluntary Verification

HouseCarers has the most thorough voluntary verification system of any platform, and importantly, it is free.

Rather than running its own identity check through a third party, HouseCarers allows sitters to upload a photo ID document directly. The photo is encrypted during transit to their servers and deleted immediately after verification is confirmed. The sitter then receives a verified badge on their profile. No personal data is retained beyond what's needed to confirm the verification has been completed.

What makes HouseCarers stand out is that this ID verification is one part of a broader voluntary system that includes police check uploads, reference and document uploads, two-way verified reviews, mobile phone verification by text code, and email verification. Sitters can also upload a video introduction. A sitter who completes the full voluntary profile ends up with one of the most credible and transparent public profiles available on any house sitting platform.

None of it is mandatory, but the comprehensiveness of what's available, and the fact that none of it costs anything, makes HouseCarers a particularly strong option for sitters who want to demonstrate trustworthiness beyond the standard review history. Our HouseCarers review covers the platform in full.

Nomador: Free ID Verification, Strongly Encouraged

Nomador takes ID verification seriously, describing it on their platform as a necessary step to lay the foundation of trust. They actively encourage all subscribed members to upload proof of identity before contacting homeowners, and list "Secured Identity check for members" as one of the platform's core features.

The check is free and available to all members, though it is not technically mandatory. In practice, Nomador frames it as an expected part of building a credible profile rather than an optional extra. The platform's broader trust system works in layers: ID verification provides the identity foundation, the internal messaging system allows both parties to get to know each other over time, and a badge and recommendation system rewards experienced members with visible markers of credibility based on review history.

There is no criminal background check on Nomador. Our Nomador pricing guide covers the full platform including what each membership tier includes.

HouseSitMatch: ID Checks as Standard

HouseSitMatch includes ID checks as a standard part of profile creation for all sitters. According to the platform, all sitters create verified profiles with ID checks, references, and reviews from previous sits, and the team provides member support to help ensure safe, positive matches. The verification is part of the standard onboarding process rather than an optional add-on.

There is no criminal background check available through HouseSitMatch.

What the Checks Actually Tell You, and What They Don't

Here is the honest version of what all of this means. An ID check confirms identity. That's it. It tells you that the person on the video call is the person whose name is on the account. It does not tell you whether they are careful with animals, whether they will respect your home, whether they communicate well under pressure, or whether the sit will go smoothly.

A criminal background check adds a layer of screening for serious past offences. It is a more meaningful check. But there are plenty of documented cases of people who have passed background checks and still turned out to be unreliable or difficult as sitters or homeowners. The check provides a filter, not a guarantee.

The barrier argument is worth making clearly. TrustedHouseSitters costs more than most other platforms. Getting on the platform requires completing ID verification. For US sitters, a background check is also part of the process. Someone who has gone through all of those steps, paid for membership, completed verification, built up a review history, and is actively maintaining their profile, has significantly more at stake than someone on a free platform. The investment itself is a form of vetting. The higher the barriers someone has voluntarily crossed to be on a platform, the more likely they are to be protective of their standing on it.

What Actually Matters More Than Either Check

We say this in almost every article about trust and vetting, and the experience across 20 sits consistently confirms it: the video call is the most important thing.

A well-conducted video call tells you things that no database can. How the person communicates, whether they've actually read the listing, whether they ask about your pets by name, whether something feels slightly off in a way you can't articulate but shouldn't ignore. We've said this from our own experience as sitters, and homeowners consistently report the same from theirs.

An ID check tells you the name is real. A video call tells you whether the person behind that name is the right fit for your home.

The other major factor is the review history. A sitter with a long history of detailed, specific reviews from multiple homeowners across multiple sits has demonstrated trustworthiness in a way that any formal check only gestures at. Reviews are public, cross-referenced, and built up over time, which makes them far harder to fabricate than a one-time verification badge. The TrustedHouseSitters blind review system covers how the review process works to keep feedback honest on both sides.

References also matter. TrustedHouseSitters asks for external character references as part of profile completion. HouseCarers allows reference document uploads. A sitter who can provide a reference from a previous homeowner, particularly one who is contactable, adds a layer of trust that no automated check replicates.

Our building trust as a new sitter guide covers how to establish credibility before a review history exists. The what to ask a homeowner before a house sit guide and the what house sitters wish homeowners knew article cover the broader picture of what actually makes a sit go well on both sides.

A Note on How Often Things Go Wrong

One thing worth stating clearly, because forums and community discussions can skew the impression: the vast majority of house sits go well. Based on the size of the community and the volume of sits completed globally, somewhere in the region of 98% of sits conclude without any serious issue.

The reason negative stories feel so numerous is the same reason negative stories feel numerous in any community. Something going wrong is worth posting about. Something going right, which is almost every sit, gets buried under the sheer volume of positive experiences that nobody writes about because there's nothing to report.

ID checks and background checks exist for the fraction of situations where they might matter. For the overwhelming majority of sits, what determines the outcome is the care both parties took during the vetting process, the quality of the communication beforehand, and the mutual respect that both parties bring to the exchange.

Conclusion

TrustedHouseSitters is the only major platform with a standardised, mandatory verification process and the only one with a criminal background check of any kind, currently limited to US sitters only. HouseCarers offers the most comprehensive voluntary verification of any platform, entirely free. Nomador strongly encourages ID verification as a necessary step for all subscribed members. The country-specific platforms, Aussie House Sitters, House Sitters America, Kiwi, Canada, and UK, all offer optional paid ID checks at around $5. HouseSitMatch includes ID verification as a standard part of sitter profile creation.

None of this changes the most important fact about trust in house sitting: the video call, the message history, and the reviews are the tools that actually tell you whether you've found the right person. The checks are a useful layer. They are not the foundation.

Caro and I have completed 20 house sits across 12 countries, driven 19,000km across Europe in our 1998 VW T4, and saved over $26,500 in accommodation costs over three years of house sitting.

Frequently Asked Questions

• Which house sitting platform runs the most thorough background checks?

  TrustedHouseSitters is the only major platform with both mandatory ID verification for all sitters worldwide and a free criminal background check, currently limited to US-based sitters only. Both are run through Evident, an accredited third-party provider. No other major house sitting platform currently runs criminal background checks.

• Is a background check available on Aussie House Sitters?

  No. Aussie House Sitters offers an optional ID verification for a one-off fee of around $5 AUD, run through Trulioo Global Gateway. This confirms identity but does not include a criminal background check. The verification is optional and displays as a badge on the sitter's profile.

• Does Nomador run background checks?

  No. Nomador offers free ID verification that is strongly encouraged for all subscribed members before they contact homeowners, and describes it as a necessary step to establishing trust on the platform. There is no criminal background check. The platform's broader trust system relies on ID verification, its internal messaging system, and a badge and recommendation system based on review history.

• Does HouseCarers charge for ID verification?

  No. HouseCarers offers free photo ID verification, and the photo is deleted from their servers as soon as verification is confirmed. The voluntary system also includes free uploads of police checks and references, phone and email verification, and two-way reviews. It is the most comprehensive free voluntary verification system of any major house sitting platform.

• Is an ID check or background check the most important part of vetting a house sitter?

  No. The video call is consistently the most important part. An ID check confirms identity. A video call tells you whether the person communicates well, whether they've genuinely engaged with your listing, and whether the fit feels right. Reviews from multiple previous sits across multiple homeowners are also a stronger long-term indicator of reliability than any one-time verification check.

• How often do house sitting arrangements go wrong?

  The vast majority go well, around 98% by most reasonable estimates of the community's size and volume of completed sits. Negative experiences get discussed far more than positive ones because problems generate conversation in ways that smooth, successful sits don't. Background checks and ID verification exist for the fraction of situations where they might matter, but the primary determinant of a good sit is the quality of the vetting process and the communication between both parties beforehand.
