Numbering Plan Update 2026-03-26 - Germany Overdialling, again

Germany Overdialling: New max_length Validation Rules

Following a download customer complaint, we found some German numbers were sometimes being incorrectly rejected, despite the e164 data being generously in line with the allocated number ranges in Germany plus additional digit length.

After some back and forward between the e164 team, the client, a transit carrier, and Telekom Deutschland, we found that the previous "overdialling" rules had not been wide enough.

Overdialling requirement: A German interconnect provider might send 496927xxx-x as the calling party number, where 496927xxx is the real subscriber number and the trailing digits represent the caller's internal extension. This is standard practice for some German enterprises — the switchboard number is sent in the P-Asserted-Identity header so return calls reach the central number, even when calling from an individual extension, but sometimes it is also possible to dial the extended number (including the extension) and be connected directly to the extension.

Previous fix (Oct 2025): Our previous approach was a blanket override extending German geographic numbers up to a maximum of 13 digits. However, due to the setup in the German numbering plan and previous short-length allocations before the liberalization of the telecoms market, this caused prefix collisions. A single number could match multiple providers at different prefix lengths, making reliable routing impossible. For example, 4932991xxxxxx was matching three separate prefixes (493, 4932, and 4932991) because the override extended all of them to 13 digits, even though they are different operators for this same prefix depending on the telephone number length.

The new fix: We redesigned the blanket Germany override with a collision-safe overdialling algorithm:

  • German GEOGRAPHIC and VOIP prefixes are extended by up to 2 digits beyond their official maximum length
  • The extension is automatically capped where it would collide with a longer (child) prefix's range — preventing the multi-match problem
  • Where a prefix is capped due to a child, gap-fill prefixes are created to ensure overdialled numbers are still covered at the correct specificity
  • The E.164 maximum of 15 digits is always respected

For example for phone number 4932991xxxxxx:

Prefix

Allocated Max Length

New Overdialling Max Length

Capped max: child 4932 starts at 10

Full max: full +2 extension

Result: All previously reported mismatches now resolve to a single, correct provider match. If you have a key to download the whole e164 database, you will find data has been automatically updated this week.

As always you can test phone numbers against the live e164 dataset on the website, for example: www.e164.com/4932991111111

Open questions we are investigating - please let us know if you have any input on these:

  1. Max_length extension depth: Are 2 extra digits sufficient for Germnay, or should we extend up to the 15-digit E.164 maximum? Some enterprises may use 3-4 digit extensions. We discussed maximum number length recently with the chair of the ITU-T SG2 E.164 group, who emphasised staying within the 15-digit ceiling.
  2. Service types: We currently apply overdialling only to GEOGRAPHIC and VOIP. Should premium rate and other service types also be included?
  3. Other countries: Is Germany unique in this practice? Liechtenstein is a candidate to investigate — they often have interesting numbering rules and their regulator is responsive to enquiries.

We would very much welcome feedback from newsletter subscribers on any of these points above.
