# Submitting via Email

### Step-by-Step Process

#### Step 1: Prepare the List of Phone Numbers

Ensure the list of phone numbers is available and formatted correctly. The phone numbers must begin with the Philippines country code (63). Example format:

639170000001\
639170000002\
639170000003

#### Step 2: Hash the Phone Numbers Using SHA-512

Use a tool that supports the SHA-512 algorithm to hash the phone numbers.

The CSV file should contain only one column with the hashed values of the phone numbers.

#### Step 3: Create the CSV File

Ensure the CSV file contains only one column with the hashed phone numbers.

Example CSV format:\
\
09f44b1394a9d6e1b153f95e65684b6da97a9cd36914357ca3011\
2fce96459f87c8b0898bce21e0f71b0f81ca24150f56b4c0bb157

#### Step 4: Submit the CSV File via Email

Once the CSV file is created, attach it to an email and send it to <devops@lenderlink.ph>.

The subject of the mail should be the company name of the contributor.

#### Step 5: Verification

Once the email has been sent, ensure to check for any confirmation or response from the DevOps team regarding the receipt and processing of the file.
