Short answer: paste the ID. A green result means the local part and handle are well formed; the handle row tells you which PSP it belongs to when that handle is in the published list.
The two halves
name@okhdfcbank is a local part, an @, and a handle. The local part is chosen by the user (letters, digits, dot, hyphen, underscore); the handle is issued by the PSP. Because the handle determines the network, a typo in it is the difference between paying the intended person and paying a stranger — which is why the payment app’s name confirmation screen exists.
What to do with a green tick
- Copy it carefully. The form is the same; the characters are not.
- Read the handle row. If it says “not in this list”, treat that as a prompt to check the spelling rather than a verdict.
- Let the app resolve the name. That step is the only proof the address belongs to the person you mean.
