Hey @thub - You can search any past receipts you have with a Square merchant at gosq.com by entering the transaction information. Once you've found your receipt, you can reach out to our Support team directly (I Don't Have A Square Account > Other > I Don't See My Issue > Email Support) and send them a copy of the receipt to have them manually unlink the phone number that is currently connected to your card. Once it's unlinked, you will be prompted to enter your correct phone number the next time you visit a Square merchant. 🤙🏼
