What is a UPI number?
A UPI number is a unique 8, 9, or 10 digit number that can be used as a payment address to receive UPI payments on any payment app. The mobile number you've used to register on payment apps will be your 10-digit UPI number.
Your UPI number will be your PhonePe registered mobile number, and will be linked to a UPI ID (VPA) in NPCI’s (National Payments Corporation of India) database. Any money sent to you using this UPI number, from any payment app, will be credited to the account that was set as the primary bank account at the time your number was added to the database.
