# IdentifierDto

ContactManager DTO used by the provider API integration layer.

## Purpose
- Carry ContactManager request or response data for provider integration workflows.

## Context
- Namespace: `SAIF.Business.Provider.Api.ContactManagerDTOs`
- Assembly/package: `SAIF.Business.Provider`

## Public members
| Member | Signature | Purpose |
| --- | --- | --- |
| offcialIDSeqNumber | `Property offcialIDSeqNumber As String` | Exposes the offcial ID seq number value on the DTO. |
| officialIDType | `Property officialIDType As String` | Exposes the official ID type value on the DTO. |
| officialIDValue | `Property officialIDValue As String` | Exposes the official ID value value on the DTO. |

## Behavioral notes
- This type is used as an API payload contract rather than as a BOF-persisted business object.

## Constraints and usage notes
- Populate instances through the provider API adapter or translator code paths that own serialization and deserialization.
