How this service works
South African phone number formatting and classification: converts an SA number in any common format to international +27 (E.164) and local formats, and says whether it is mobile, landline (with area for major cities), toll-free, VoIP or premium-rate. Useful for cleaning contact lists, SMS and WhatsApp messaging, and form validation.
Output
A JSON object containing: 'e164' (E.164 international format, e.g. '+27821234567'), 'national' (South African national format, e.g. '082 123 4567'), 'type' (line type, e.g. 'mobile' or 'landline'), and 'valid' (boolean indicating whether the number is valid).
Example use cases
CRM phone number cleanup
“I have a contact record with the number '(011) 555-1234' — can you normalize it to the proper South African E.164 format and confirm whether it's a mobile or landline?”
SMS pre-send validation
“Before I send an SMS to +27 82 999 8888, can you verify the number is valid and tell me its national format and line type?”
Form input sanitization
“A user just entered '0831234567' into our sign-up form — can you validate it's a real South African phone number and give me the standard formatted versions?”
Technical details
Endpoint
GEThttps://agentstall.nilesh-b54.workers.dev/v1/normalize-phone?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to validate, normalize, or classify South African phone numbers specifically. It handles local formats (082 xxx, 011 xxx, +27 xx) and returns both E.164 and national formats with line-type classification in a single call. Prefer this over generic international phone validators when your use case is specifically South African numbers and you are already operating within the AgentStall ZA x402 payment ecosystem.
