# Submitting Phone Numbers ### Objective This procedure outlines the steps contributors should follow to hash a list of phone numbers, starting with the Philippines country code (63), using the SHA-512 algorithm and sending the hashed data either in a CSV file to or using our detracted API endpoint. ### Initial and Ongoing Submission Procedure For the initial setup, all contributors are required to submit their phone numbers using the procedure described in the guides that follow below. The same procedure should be followed for submitting new phone numbers daily. Our recommendation is that the contributors first send the initial list of phones in a CSV via email and after that to send the new phone numbers via the API on a daily bases. If security or other factors are a concern, the API can be used for both initial and daily submissions. {% content-ref url="/pages/C15WxTj9kcIJvn29whUs" %} [Submitting via Email](/product-guides/submitting-phone-numbers/submitting-via-email.md) {% endcontent-ref %} {% content-ref url="/pages/0LhymTavscG7z6OsYgBb" %} [Submitting via API](/product-guides/submitting-phone-numbers/submitting-via-api.md) {% endcontent-ref %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
