## Fields on this page

Layout controls in source order, grouped by the container they sit in. Shows: the table field a control is bound to (or its expression as written); ToolTip: the control's own, else the bound field's (marked).

| Group | Control | Shows | ToolTip |
|---|---|---|---|
| Control1 | Code | [Code](../table/225.md#fields) | Specifies the postal code that is associated with a city. <small>from the table field</small> |
|  | City | [City](../table/225.md#fields) | Specifies the city linked to the postal code in the Code field. <small>from the table field</small> |
|  | Country/Region Code | [Country/Region Code](../table/225.md#fields) | Specifies the country/region of the address. <small>from the table field</small> |
|  | County | [County](../table/225.md#fields) | Specifies a county name. <small>from the table field</small> |

## Relations

- source table [Table 225 "Post Code"](../table/225.md)

## Pages and codeunits on this table

- [Table 225 "Post Code"](../table/225.md) (lookup page)

## Called by

From the extracted call graph of BC29 (graphify-al on the snapshot checkout): calls whose target is known from a declared type or an `Object::"Name"` argument. Interface dispatch and calls through events are not counted, so the list is not complete.

- [Table 225 "Post Code"](../table/225.md) (2 calls: `ValidateCity → (object)`, `ValidatePostCode → (object)`)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC27

## Documented on Microsoft Learn

- [Register new customers by creating a Customer Card](https://learn.microsoft.com/dynamics365/business-central/sales-how-register-new-customers)

Source: AL metadata extracted from the code (names, ids, signatures, properties); no code bodies (D10).

## Ask your agent

Procedure bodies are not stored here (D10). The call sections above are our own, per object, from the BC29 call graph. For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: `bcatlas_resolve_node(object_type: "page", object_name: "Post Codes")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
