Super hard to do correctly. If someone wants to make a specific API proposal here, I'm all ears. But this is the kind of thing that's almost impossible to make everyone (or even most people) happy.
Validation for E.164 phone numbers could be added via regex. It should validate most, albeit not all e164 numbers, correctly. See documentation from Twilio/Sendgrid: https://www.twilio.com/docs/glossary/what-e164#regex-matching-for-e164

You can achieve this easily yourself with something like the following, and using libphonenumber-js at least somewhat guarantees good results:
import parsePhoneNumber from "libphonenumber-js";
import * as z from "zod";
/**
* Zod schema that validates a phone number using `libphonenumber-js`.
* Attempts to parse the provided value with a default country of `FI`.
*
* If the phone number is valid, the schema transforms the phone number into
* an international format (e.g. `+358401234567`).
*/
export const zPhoneNumber = z.string().transform((value, ctx) => {
const phoneNumber = parsePhoneNumber(value, {
defaultCountry: "FI",
});
if (!phoneNumber?.isValid()) {
ctx.addIssue({
code: z.ZodIssueCode.custom,
message: "Invalid phone number",
});
return z.NEVER;
}
return phoneNumber.formatInternational();
});
At react-international-phone they recommend using google-libphonenumber for validation. Maybe Zod can rely on that for integrated phone validation as well?
The idea is using a zod schema like z.string().phone() and let parse any phone number format valid world-wide.
