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. | Number | What happens | | - | - | | +49 30 84581026 | Answers with "Hallo, hier ist Markus von der Buchhaltung.", stays silent for 30 seconds, then hangs up. | | +49 30 84581038 | Answers with "Hallo, hier ist Nina vom Kundenvertrieb. Freut mich, dass Sie mit uns in Kontakt getreten sind.", stays silent for 30 seconds, then hangs up. | | +49 30 84581247 | Answers with "Hallo, hier ist Jonas von der Stornoabteilung.", stays silent for 30 seconds, then hangs up. | | +49 30 84581296 | Rings for about 10 seconds and never answers. | For example, in your guidance: ```text theme={null} Available hotlines: - Accounting: +49 30 84581026, available 9:00–17:30 (CEST) - Sales: +49 30 84581038, available 9:00–17:30 (CEST) - Cancellations: +49 30 84581247, available 9:00–17:30 (CEST) - Travel service: +49 30 84581296, available 9:00–17:30 (CEST) ``` ### 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](#demo-transfers) when you need a number that answers. **Germany.** The Bundesnetzagentur reserves these [drama numbers](https://www.bundesnetzagentur.de/DE/Fachthemen/Telekommunikation/Nummerierung/DramaNumbers/artikel.html): | Area | Numbers | International format | | - | - | - | | Berlin | 030 23125 000 to 999 | +49 30 23125000 to +49 30 23125999 | | Frankfurt am Main | 069 90009 000 to 999 | +49 69 90009000 to +49 69 90009999 | | Hamburg | 040 66969 000 to 999 | +49 40 66969000 to +49 40 66969999 | | Köln | 0221 4710 000 to 999 | +49 221 4710000 to +49 221 4710999 | | München | 089 99998 000 to 999 | +49 89 99998000 to +49 89 99998999 | | Mobile | 0171 39200 00 to 99 | +49 171 3920000 to +49 171 3920099 | | Mobile | 0176 040690 00 to 99 | +49 176 04069000 to +49 176 04069099 | | Mobile | 0152 28817386, 0152 28895456, 0152 54599371, 0172 9925904, 0172 9968532, 0172 9973185, 0172 9973186, 0172 9980752, 0174 9091317, 0174 9464308 | +49 152 28817386 and so on | 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.** | Country | Numbers | Source | | - | - | - | | United Kingdom | Mobile 07700 900000 to 900999, London 020 7946 0000 to 0999, any area 01632 960000 to 960999, plus ranges for other cities | [Ofcom](https://www.ofcom.org.uk/phones-and-broadband/phone-numbers/numbers-for-drama) | | United States and Canada | 555-0100 to 555-0199 after an area code, for example +1 202 555 0100 | [NANPA](https://nanpa.com/numbering/555-line-numbers) | | France | 01 99 00 xx xx, mobile 06 39 98 xx xx, plus one range per region | [ARCEP](https://www.arcep.fr/uploads/tx_gsavis/25-2215.pdf) | | Ireland | Mobile 089 011 0000 to 0999, and 020 xxx xxxx | [ComReg](https://www.comreg.ie/media/2024/04/ComReg-15136R4.pdf) | | Sweden | Mobile 070-174 06 05 to 06 99, Stockholm 08-465 004 00 to 004 99, plus ranges for other cities | [PTS](https://pts.se/sv/nyheter/telefoni/2020/pts-reserverar-nummerserier-for-film-och-bocker/) | 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](https://docs.stripe.com/testing?payment-method=sepa-direct-debit). | IBAN | Outcome in Stripe test mode | | - | - | | DE89 3704 0044 0532 0130 00 | Payment succeeds | | DE08 3704 0044 0532 0130 03 | Payment succeeds after at least three minutes | | DE62 3704 0044 0532 0130 01 | Payment fails | | DE78 3704 0044 0532 0130 04 | Payment fails after at least three minutes | | DE35 3704 0044 0532 0130 02 | Payment succeeds, then the customer disputes it | | DE84 3704 0044 0000 4545 45 | Payment fails and the mandate is revoked | | DE65 3704 0044 0002 2222 27 | Payment fails for insufficient funds | | DE65 3704 0044 0000 3434 34 | Payment fails, weekly payment volume exceeded | | DE27 3704 0044 0000 1212 12 | Payment fails, weekly transaction limit exceeded | | DE18 3704 0044 0000 0666 66 | Stripe rejects the account as unusable | 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: * [Simulate a payment by card brand](https://docs.stripe.com/testing?payment-method=sepa-direct-debit#cards) * [Simulate a payment by country](https://docs.stripe.com/testing?payment-method=sepa-direct-debit#international-cards) * [Simulate a declined payment](https://docs.stripe.com/testing?payment-method=sepa-direct-debit#declined-payments) The most common ones: | Card | Number | Outcome in Stripe test mode | | - | - | - | | Visa | 4242 4242 4242 4242 | Payment succeeds | | Mastercard | 5555 5555 5555 4444 | Payment succeeds | | Visa, issued in Germany | 4000 0027 6000 0016 | Payment succeeds | | Visa | 4000 0000 0000 0002 | Declined | | Visa | 4000 0000 0000 9995 | Declined for insufficient funds | Use any future expiry date, such as 12/34, and any three-digit CVC. ## Next steps > [card] [Simulations](https://docs.botbrains.io/guides/simulations.md) > > Run test conversations with this data and check the outcome. > [card] [Phone](https://docs.botbrains.io/concepts/phone.md) > > Set up forwarding to your team's numbers.
