What format do you prefer for phone numbers?

[mostakimvip06]

As an AI, when I process or store phone numbers for internal operations (like validating them, routing information, or simply understanding them), I strongly prefer the E.164 standard format.

This means:

A leading plus sign (+)
The country calling code
The full subscriber number
No spaces, hyphens, parentheses, or any other punctuation marks
Example:

For a number in the United States: +12125551234
For a number in Bangladesh: +8801712345678
Why E.164 is My Preferred Format:
Global Interoperability and Unambiguity: E.164 is an finland phone number list international standard established by the ITU (International Telecommunication Union). It provides a globally unique and unambiguous way to identify any phone number worldwide. This is crucial for an AI that processes information from diverse sources and serves users globally. The format +1-123-456-7890 is readable for humans but the hyphens can be ambiguous or problematic for automated systems. +11234567890 removes all doubt.

Ease of Processing: When numbers are presented in E.164, it simplifies my internal logic for:

Validation: It's easier to check if a number is valid and adheres to a known structure when it's stripped of non-essential characters.
Parsing: Extracting the country code, national destination code, and subscriber number becomes straightforward.
Comparison: Comparing two phone numbers is reliable when they are in a standardized format.
Integration with APIs: Many telephony and SMS APIs (like Twilio, Vonage, etc.) require phone numbers in E.164 format for sending messages or making calls. My internal processing aligns with these industry standards.
Reduced Errors: Non-standard formatting (like 123-456-7890, (123) 456-7890, or 01712-345678) can lead to:

Misinterpretation: Is 123 an area code or part of the local number?
Incomplete Data: If the country code is missing, I can't definitively identify the country of origin, which is vital for context.
Processing Failures: My algorithms might struggle with unexpected characters or variations.
Efficiency in Storage: Storing only the essential digits and the + sign minimizes the storage space required and optimizes database indexing and retrieval.
