tel: Link International Format
Format bounded E.164-like digit shape as global tel URI; no country-code, number assignment or caller identity validation.
Description
tel: Link International Format: return tel uri, assigned number verified.
A telephone URI identifies a dialing target, while a digit-shape check says nothing about whether a number is assigned. International digits need an explicit format.
This tool returns tel uri, assigned number verified. Use the stated units and model convention when interpreting these fields.
When to use this tool
Use this tool when the supplied inputs match the specific operation described above and you need a repeatable result under its stated convention.
- Check the supported input and output contract against an existing calculation or observation.
- Use the complete example to confirm units, selector spelling and result interpretation.
How to use the tool and how it works
- Enter every field in the input table using the stated units and the exact supported selector spelling where applicable.
- Run the tool. Correct input errors before interpreting an output.
- Read the result fields below; use accompanying flags and the stated sign, boundary or model convention when interpreting a number.
Require 2–15 ASCII digits beginning with a nonzero digit, without a leading plus. Prefix tel:+ to form telUri.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| e164Digits | E164 digits. | Text |
| Output field | Interpretation |
|---|---|
| result | Object containing the following named result fields. |
| result.telUri | Tel uri; use the stated units and sign convention. |
| result.assignedNumberVerified | Always false; telephone allocation is not checked. |
{
"input": {
"e164Digits": "12025550123"
},
"output": {
"result": {
"telUri": "tel:+12025550123",
"assignedNumberVerified": false
}
}
}Limitations and assumptions
- assignedNumberVerified is false. Country-code validity, extensions, allocation and reachability are not checked.
- Every declared field is required and unexpected fields are rejected. Numeric inputs must be finite; input errors are distinct from a valid false result or an explicitly qualified output.
- Extremely large inputs and nonfinite or excessively large outputs are rejected. List positions reported by the tool use zero-based indices unless stated otherwise.
Alternative or Complementary methods
Check the underlying observations, units and conventions independently before using the result in a larger workflow. The tools listed below address nearby tasks; compare their inputs and scope before substituting one for this operation.
