- **How it is detected:** Deterministic (settled in code from the submitted values)
- **Fix type:** Fix the field — a better value in the form clears it
- **Required by:** Bandwidth, AWS
- **Applies:** Applies to every 10DLC registration.
- **Canonical URL:** https://ekas.io/rules/10dlc/campaign/cmp-016/

## Why this rule exists

A space inside a contact address is the single most common field-hygiene rejection, and it survives because the space is usually trailing — copied along with the address out of a spreadsheet cell or an email signature. The address looks right in the form and is unusable to anything that parses it.

## How to fix it

Retype the contact email and phone rather than pasting them, or trim the value in a plain-text editor first. Done when neither field contains a space at the start, the end, or in the middle.

## Example of a compliant value

```text
contact email: support@acmecoffee.com · contact phone: 415-555-0134
```

## Provider rejection codes

| Provider | Code | Resubmission allowed |
| --- | --- | --- |
| Bandwidth/DCA | `6102` | yes |

## Notes

Bandwidth 6102 verbatim: "The email and/or phone number must not contain any spaces." The catalog states this row more broadly as "spaces or special characters"; that wording traces to a secondary reseller paraphrase of the same code, so only the spaces half is asserted here. Separators inside a phone number are governed by the E.164 formatting rule on the brand, not by this one.
