REGISTRATIONSet the number before you deposit
Registration asks for the details that identify your account, and the phone number is the one to get right first. Use a number you control, that you can answer messages on, and that is the same wallet number you plan to pay from. The published pages do not say how a registered number is changed later, so check with support through the chat icon at the bottom of Baji's website before you change it.
Use your own number
Choose a number you control and can answer messages on, since your account may send you notices about it.
Match the wallet
Use the number your Easypaisa wallet is registered to, since the Easypaisa deposit is sent from it. For withdrawals, the help centre says the wallet account must match the registered phone number, so one number on both sides is the safer choice.
Keep it current
Write down the number you registered. The help centre notes that support can add up to three phone numbers to one account.
Check before paying
Compare the number on your account with the wallet number before you pay, so the payment can be traced back to the account.
