# Introduction
close https://github.com/twentyhq/twenty/issues/12343
Adding a transform step for any field phone in order to infer country
code and calling code from the number if they're provided
## Edges cases
```ts
RecordTransformerExceptionCode.INVALID_PHONE_NUMBER:
RecordTransformerExceptionCode.INVALID_PHONE_COUNTRY_CODE:
RecordTransformerExceptionCode.CONFLICTING_PHONE_COUNTRY_CODE:
RecordTransformerExceptionCode.CONFLICTING_PHONE_CALLING_CODE:
RecordTransformerExceptionCode.CONFLICTING_PHONE_CALLING_CODE_AND_COUNTRY_CODE:
RecordTransformerExceptionCode.INVALID_PHONE_CALLING_CODE:
RecordTransformerExceptionCode.INVALID_URL:
```
## Coverage
Note: Will handle REST api integration testing pivot and UPDATE
operation later in the afternoon, critical bug appeared that I prefer
handling before improving this PR coverage, also would be too many
updates
Note2: Haven't fuzzed all of the string inputs, would seem overkill for
such a use case, to be debated
