How safe is to use autonumber as a receipt number?

[Silenus]

Hello everybody.
As the title says, I’m generating receipts with Airtable and I’m looking for a solution to generate a unique number for each one.
I was looking at automation to maybe grab the last record and on the receipts # field do a +1, but I think this could be simpler with autonumber.

Greatly appreciate your input.

Autonumber should be fine.

You could also use the RECORD_ID() function to show the unique & randomized record ID that Airtable has assigned to each record.

Thanks.
RECORD_ID() is great for the unique number but I would like an incrementing sequence.
