Keep getting error code 5p339z7q

[zurvyog]

I used to be able to reply to messages and  now I can't for some reason. It says I have to add a phone number and when I go to do that it says my number isn't a US number, then it gives me an error code (5p339z7q)

My phone number is a US number and nothing works. Please help.

Are you using an internet phone number like Google voice? As of right now, Offerup doesnt allow the use of internet numbers. If not, I would try contacting support. https://offerup.com/support/new

I have sent them an email since what you mentioned doesn't pertain to me. I have service from ATT and have used my number for multiple verifications, I don't know why OfferUp is giving me issues all of sudden.
