01 / Dialing & E.164 Formatting Guide

How to Enter a South Korea (+82) Number in OpenAI / ChatGPT

Over 20% of failed international OTP deliveries happen because of duplicate country codes or unstripped domestic trunk prefixes. Follow the exact South Korea (+82) formatting rules below when verifying OpenAI / ChatGPT:

Option A · Country Flag Selected in OpenAI / ChatGPT

National Subscriber Digits Only

1012345678

When you select 🇰🇷 South Korea (+82) from OpenAI / ChatGPT's country dropdown, paste only the subscriber digits above without repeating +82.

Option B · Full International Input Field

ITU-T E.164 Full String

+821012345678

If OpenAI / ChatGPT or your API testing script asks for a single international E.164 phone string (Display format: +82 10-1234-5678), include the leading +82 prefix.

Critical Telecom Rule · KR (+82)

Domestic Trunk Prefix Policy

Strip the domestic leading trunk "0" when dialing internationally with +82 (e.g., domestic 0101... becomes +82 1012345678).

OpenAI / ChatGPT Pro Tip: Ensure you select "Send code via SMS" (not WhatsApp) during the OpenAI verification prompt, and use a supported country code that matches your current connection region.
