Burger Service Nummer/Social-fiscal Number

After registration with the municipality you receive a Burger Service Nummer; if this registration is not possible for you for whatever reason, then you have to apply for a Social-Fiscal Number at the tax-office in Rotterdam. Non-EU-students can only do so after obtaining their residence permit. For more information on this: 0800-0543. EU-students can of course apply for this without a residence permit.
