I was going through plaid docs and I found this "In some instances, account IDs may change." So now I am curious how can i uniquely identify an account. ref https://plaid.com/docs/api/ in the Item Management section.

I want to uniquely identify an account because that is what user selected to use as primary account.

Any recommendations are welcome.

I believe mostly it will be unique unless some changes are applied in the bank side like removing/adding account type to the existing ones. Also even if we use same account more than once, plaid will assign unique ID as account_id each and every time.

I prefer, you should go by the account & routing number and not by the account_id returned by plaid. Account_id is mainly used for plaid reference.

I realize this is an old question, but I just wanted to confirm for anyone who finds this that the account_id is not a unique identifier. Instead, the access_token should be used to identify an account in your database.

If you're using plaid/dwolla to initiate ACH payments, the dwolla funding URL is the best identifier of the account.
