When adding a signer, you must enter his/her telephone number so that he/she can receive the security code by SMS, enabling him/her to authenticate and sign.

If your signer has a foreign telephone number, simply enter the relevant country code when adding the signature field.

For example: GB country code is +44, France is +33, Italy is +39

Our Yousign electronic signature services are designed to send security codes by SMS message or by voice server over more than 220 countries around the world.

Some operators do not accept certain number aliases.

To maximize your chances of reception, please use the following codes:

  • Guadeloupe (+590)

  • Reunion Island (+262)

  • French Guiana (+594)

  • Martinique (+596)

  • Mayotte (+262)


The formatting of these numbers often makes it impossible to determine whether it's a mobile or a landline. As a result, the authentication code is often transmitted directly by voice server.

You can tell the signer to be close to their landline when signing.
