0041

0041 is a four-digit numeric string commonly encountered in international telephone dialing. It represents the country calling code for Switzerland when used with an international access code. The official country code for Switzerland is 41, and 0041 is one common way to express dialing to Switzerland from countries that use 00 as their international prefix. In international contexts, the plus sign (+) is also standard, yielding +41.

In practical use, dialing from abroad involves entering the international prefix, followed by 41, then the Swiss local number. The leading zero of the local area code is typically omitted. For example, a domestic Zürich number written as 044 123 4567 would be dialed from abroad as 0041 44 123 4567 or [phone]. The 00 prefix is a common international dialing prefix in many regions.

Other contexts: In computing, 0x0041 is the hexadecimal encoding for the Unicode code point U+0041, which corresponds to the capital letter A. The string 0041 may also appear as a numeric identifier or as a year designation (Year 41 CE) in historical references.
