Can one add a payment id to a subaddress? When withdrawing from an exchange you can put in a payment id and a subaddress. Will it work?


A payment ID is part of a transaction, not an address. Therefore, yes, if the exchange supports adding a payment ID field, it will be added to the transaction and you can view the payment ID in your wallet incoming transfers.

  • so yes you can combine a payment id with a subaddress? – Patoshi パトシ Aug 19 '18 at 16:12
  • As per answer, a payment id is part of the transaction. So yes, if the exchange offers payment id support. – jtgrassie Aug 19 '18 at 17:58

    @Patoshiパトシjtgrassie is talking about the old style unencrypted payment ids, and not the new style integrated address encrypted payment ids. There is no such thing as an integrated subaddress. – knaccc Aug 19 '18 at 18:57
  • so don't put a payment id with a subaddress your saying? it wont work? – Patoshi パトシ Aug 20 '18 at 16:45
  • Not quite. It depends on the exchange. If it allows you to use a payment id (as a separate field) it should be fine. There are 2 ways of using payment ID's. 1) as a separate field and 2) included in an integrated address (that is an address with embedded payment ID). – jtgrassie Aug 20 '18 at 17:49
