0211

0211 is the telephone area code for Düsseldorf, the capital city of North Rhine-Westphalia, Germany. In the German national numbering plan, the 0 that begins the code is the trunk prefix used for domestic dialing, and 211 designates the Düsseldorf area for landline numbers. Numbers in this area typically appear as 0211 followed by the local subscriber number.

Dialing conventions: Within Germany, calls to Düsseldorf landlines use the full code 0211 plus the local number. From outside Germany, callers use the international format +49 211 followed by the local number, omitting the leading 0 of the area code.

Geography and scope: Düsseldorf is a major city located on the Rhine and serves as a significant commercial, financial, and cultural center in the region. The 0211 area code covers the city itself and nearby areas that share the same landline code for telephone numbering.

Context: While 0211 primarily refers to the Düsseldorf area code, it can appear in various contexts as a numeric identifier or code in telecommunications and related documentation. The designation is specific to landline dialing and is not used for mobile numbers, which use different prefixes.
