Demo transfers
To try or show call forwarding end to end, list these botBrains test lines in your guidance instead of your colleagues’ numbers. Three answer like a department with a short German greeting. The fourth never answers, so you can test what your agent does when nobody picks up.
For example, in your guidance:
Unassigned numbers
For customer phone numbers in simulations, demos, test users and examples, use numbers that telecom regulators keep permanently unassigned for films, books and advertising. Nobody owns them, so a test can never call or text a stranger. Calls and SMS to them don’t go through, so use the demo transfer lines when you need a number that answers. Germany. The Bundesnetzagentur reserves these drama numbers:
For any other area code, put a 0 directly after the area code, for example 0371 04528562. No German subscriber number starts with 0, so the number can’t exist.
Other countries.
We know of no official list for Austria or Switzerland.
IBAN
Every IBAN on this page passes the IBAN checksum, so your tools accept it as well formed. No bank behind it. The Deutsche Bundesbank prints DE58 1234 5678 0123 4567 89 as its sample IBAN. Bank code 12345678 isn’t assigned to any bank, so the IBAN can’t reach an account. Use it wherever your tools only check the format. Stripe test IBANs. If your tools create SEPA payments in Stripe test mode, these German IBANs trigger a fixed outcome. Stripe lists them, and the Austrian equivalents, under SEPA Direct Debit test IBANs.
Outside Stripe test mode, these are ordinary IBANs at a real bank: bank code 37040044 belongs to Commerzbank. Never use them for real transfers.
Cards
Stripe’s test cards work only in Stripe test mode. Stripe lists all of them by use case: The most common ones:
Use any future expiry date, such as 12/34, and any three-digit CVC.
