My TINCheck API calls are failing randomly, getting 'invalid TIN' errors for valid numbers. Is their system having issues?

D DataDigger 3 weeks ago ✓ Best Answer
Our team actually contacted support about this yesterday. They said they were looking into some 'backend database sync issues'. No ETA on a fix though.

Ah, that explains it. Hopefully they resolve it soon.

I'm on the Basic Plan and haven't noticed anything weird. Maybe it's specific to certain API endpoints or higher volume plans?

Could be. We're on Enterprise Solutions, so maybe it's something with that.

We've had a few intermittent 'invalid TIN' responses this morning too, even for TINs that verified fine last week. Super frustrating.

Did you check their status page? Sometimes they post updates there.

Thought it was our integration. Good to know it might be on their end.

Anyone else having trouble with the '20% off annual plan' discount not applying at checkout?

C ComplianceCarl 1 month ago ✓ Best Answer
I got it to work but I had to go through their 'contact sales' page and ask them to apply it manually. Took a day or two.

Ugh, that's annoying. Was hoping for a smoother process.

Are you sure it's for the annual plan? I think some deals are just for new customers or the first month.

It says '20% off annual plan' right on their site banner, so it should apply.

Yeah, I tried to sign up for the Standard Plan last week and it just showed the regular price. Thought it was just me.

Same. Ended up just paying full price cause I needed it ASAP.

Did you try clearing your cookies? Sometimes that helps with promo codes.
