# Number

The **Number** field enables users to enter numeric data, for example, phone number or ZIP code.

This field possesses certain [properties](/docs/headless-cms/about-field-properties) that you can change any time as per your needs. The properties that can be modified are “[Display Name](/docs/headless-cms/display-name),” “[Unique ID](/docs/headless-cms/unique-id),” “[Placeholder Value](/docs/headless-cms/placeholder-value),” “[Instruction Value](/docs/headless-cms/instruction-value),” “[Help Text](/docs/headless-cms/help-text),” “Range” “[Default Value](/docs/headless-cms/default-value),” “[Mandatory](/docs/headless-cms/mandatory),” “[Multiple](/docs/headless-cms/multiple),” and “[Non-localizable](/docs/headless-cms/non-localizable).”

After you add this field in [content type](/docs/headless-cms/about-content-types), you will see it on your [entry](/docs/headless-cms/about-entries) page as shown in the example below. The **Customer Number** entry is the **Number** field content type.
