"It Just Works—Reliable Experience with TINCheck"
5/5
What do you like best about TINCheck?

Not to be too simplistic, but it does what it says on the... (drumroll) TIN. We have a set of tax information from customers that get entered and we are able to pretty seamlessly pipe in that data using the TIN API calls and communicate those results to customers. Huge win for them to have their vendor's tax info validated Review collected by and hosted on G2.com.

What do you dislike about TINCheck?

Rate limiting, which I believe is done not by TINCheck but by the IRS, can sometimes be a bit painful. We were able to implement caching on our side to group and limit and speed up the calls we make on our side, but my understanding is that this is not a TIN Check limitation, but a limitation of the core API the IRS offers Review collected by and hosted on G2.com.

"Fast, Easy Customer Verification with Clear Results"
4/5
What do you like best about TINCheck?

The best thing about TINCheck is how fast and easy it is to use. The information we need is available quickly, allowing our team to verify new customers without adding a lot of extra steps to the onboarding process. The interface is straightforward, and the results are easy to understand. It helps us maintain accurate customer records while improving efficiency, which is especially valuable when processing a large volume of new customer requests. Review collected by and hosted on G2.com.

What do you dislike about TINCheck?

Overall, we have had a positive experience with TINCheck and have not encountered any significant issues. If I had to identify an area for improvement, it would be providing additional details or guidance when records do not match or cannot be verified. More information about the reason for a mismatch could help users resolve exceptions more quickly. That said, the product performs its core function well and has met our organization's needs for customer verification. Review collected by and hosted on G2.com.

"Accurate and User Friendly"
5/5
What do you like best about TINCheck?

TIN Check is a very user-friendly website. When I enter the social security or federal ID number it provides me with the company name so I can make sure the W9 provided is legit. It has avoided many issues with at the end of the year when 1099's are due and I know all the W9's provided are correct. Review collected by and hosted on G2.com.

What do you dislike about TINCheck?

TINCheck is very user friendly but sometimes when I enter only the Federal ID number it does not provide me the name of the company, the fact that I also need to enter the name of the company it takes more time in the verification process. Once I enter the name, if it is a match, it will say result found. I feel more confident if the name of the company is shown after the FEIN only is entered. Review collected by and hosted on G2.com.

"TINCheck Makes TIN Verification Fast, Reliable, and Compliance-Friendly"
4/5
What do you like best about TINCheck?

What I like best about TINCheck is how it uses technology to simplify complex tax and compliance processes and help businesses maintain accurate information. I appreciate the practical value of a platform that can reduce manual work, minimize errors, improve data accuracy, and help organizations stay compliant with confidence.

As a Chartered Accountant, I have developed a strong understanding of accounting, financial reporting, reconciliations, tax compliance, and the importance of maintaining accurate financial records. My experience has also shown me how much efficiency can be gained by improving and automating repetitive processes. That is why I find TINCheck’s focus on technology, accuracy, compliance, and process efficiency particularly interesting. Review collected by and hosted on G2.com.

What do you dislike about TINCheck?

I would recommend TINCheck to businesses looking for a reliable and efficient way to verify tax identification information and simplify compliance processes. It helps reduce manual work, minimize errors, and make tax-related verification more streamlined. I also like that it can save time for accounting and finance teams by providing a more organized and efficient verification process. Overall, it is a useful solution for businesses that want to improve accuracy, maintain compliance, and reduce administrative effort. Review collected by and hosted on G2.com.

"TinCheck Adds Strong Tax ID Verification Security and Builds Confidence"
5/5
What do you like best about TINCheck?

We like TinCheck because it adds an extra layer of security through Tax ID verification, which helps reduce fraud risk and better protect our business. It also streamlines the verification process, improves accuracy, and gives us greater confidence that the individuals and businesses we work with are legitimate. Review collected by and hosted on G2.com.

What do you dislike about TINCheck?

While we appreciate the added security TinCheck provides, there is room for improvement in the user experience, verification speed, and handling of exceptions. Making the process more seamless and intuitive would help improve overall efficiency. Improving system speed and simplifying the verification process would make it more user-friendly and efficient.

"User-Friendly Vendor Validation That Strengthens Forecasting"
4/5
What do you like best about TINCheck?

I like TINCheck’s user-friendly interface. I can use it intuitively with little training, pull reports, and rely on accurate data. Its vendor validation helps me keep vendor names and DBAs aligned with the right TINs, track vendors and spend, and keep data clean for vendor-level forecasting. I can use its vendor reports and historical data for variance analysis and forecasting, and plug the reports into our financial models. The system works well for us, and my accounting team has found it useful too. Review collected by and hosted on G2.com.

What do you dislike about TINCheck?

TINCheck seems more accounting-focused, and I kind of have to have an accounting mind when I use it. The terminology is very accounting-oriented, so it could be more user-friendly for FP&A teams who may not know all the terms. I’m also not sure how it compares on price, and I hope to explore that more when contracts are up. Review collected by and hosted on G2.com.

"TINcheck Makes Vendor W-9 Verification Fast, Easy, and Reliable"
5/5
What do you like best about TINCheck?

The most helpful part of TINcheck is how easy it is too use the system. It provides us with a quick and efficient way to verify all data provided by a vendor on a W9. The absolute best part is it only adds a few extra minutes to our onboarding process yet provides an overwhelming assurance that we have accurate info on file. Review collected by and hosted on G2.com.

What do you dislike about TINCheck?

The least helpful part of TINCheck is that the system will occasionally go offline due to connection issues with the IRS. There have been a few times where a vendor registration got delayed due to us having to wait for the IRS verification system to come back online. Though this is not a super common occurrence it has happened enough to bear mentioning. Review collected by and hosted on G2.com.

"Strong TINCheck Search Results—Would Love Easier PDF Export"
4/5
What do you like best about TINCheck?

It was easy to start using and is easy to train new employees on. Running TINCheck gives us real-time screening results. We have the ability to batch upload suppliers. It is less expensive than other screening programs out there while still running supplier EIDs against a multitude of screening lists. Review collected by and hosted on G2.com.

What do you dislike about TINCheck?

It is not easy to export the results of the TINCheck search. We have to do a print screen and export it as a PDF. It would be better if there was a PDF generated after the results ran that had all of the information we entered along with the results. There are no ongoing monitoring or “new findings” alerts.

"Tincheck Is User-Friendly, Flexible Pricing, and Clear Results at a Glance"
5/5
What do you like best about TINCheck?

Tincheck is very user friendly and easy to read and understand. The prepaid checks allow for smaller businesses to use the service without having to commit to a monthly fee. I like that we can also upload a bulk file to run a check at year end if needed. The red and green coloring on the results provides easy to see quick glance results. Review collected by and hosted on G2.com.

What do you dislike about TINCheck?

The least thing I like at this time is that each time I login it prompts me to sign up for two factor authentication. I've clicked that I do not want to sign up for two factor authentication each time and it continues to try to get me to sign up for it. I want this to be set to where I've rejected it, and if I decide to add it I can go to my settings. Review collected by and hosted on G2.com.
