Phone Numbers

Phone numbers allow your voice agents to receive and make calls. In this section, we explain how to purchase numbers directly from Diga, so you don’t have to manage telephony infrastructure.
We currently only offer Spanish phone numbers, and calls are only allowed to national numbers. If you want to make requests for other countries, check the Configure custom number section.
This video shows how to assign real phone numbers to your agents, including identity verification and number management. The video is in Spanish.

Buy Phone Numbers

1

Select your numbers

Go to Phone Numbers and click “Buy number”. Under Prefix, choose a province or Commercial (400) and select the numbers you need. 400 numbers are for outbound commercial calls only: see 400 Numbers.

2

Complete payment

You will be redirected to Stripe to process the payment securely. The numbers will be reserved for your project.
3

Verify your identity (if needed)

If this is your first purchase or you buy numbers in a new province, you must complete identity verification before the numbers are activated. You have 24 hours to complete this step.
4

Configure your agents

Once active, assign agents to your numbers so they can receive and make calls.
Numbers reserved during purchase will be kept on hold until identity verification is completed.

​
Identity Verification

​
Why is it Necessary?

Identity verification is a regulatory requirement to prevent fraud and comply with telecommunications regulations. It proves two things: your company’s identity, and that your company has an office in the province of each geographic number you buy.

​
When is it Required

When you buy, we only ask for what is missing:
If your project was already verified, the provinces of the numbers you already had count as proven. Ceuta and Melilla share prefixes with Cádiz and Málaga, so for those numbers an invoice from either province works.

​
Verification Process

Identity is verified with PDF documents:
  • The digitally signed verification document proves your company’s identity. It is only required until your project is verified.
  • The province-related invoice proves that your company has an office in the province for the number. It can be an electricity, water, gas or rent invoice issued in the last 6 months, or a business deed with the correct registered address. If you buy in several new provinces, the invoice must prove all the provinces we list. 400 numbers don’t need it.
The process is as follows:
1

Complete your purchase

After entering your payment information, your numbers will be temporarily reserved. You won’t be charged until your identity is verified.
2

Download the document (first verification)

A verification step will appear with a document to download.
3

Sign with your digital certificate (first verification)

Sign the document using your company or self-employed (autónomo) digital certificate.
4

Upload the PDFs we ask for

The verification step tells you what you need: the signed document, the invoice for the missing provinces, or both.
5

Wait for approval

Your number will be reviewed in less than 24 hours. You will receive all the information by email.
6

Automatic activation

Once approved, your reserved numbers will be automatically activated.

​
Verification States

Your verification can be in one of these states: Pending
  • Documents submitted, awaiting review
  • You cannot purchase additional numbers during this period
  • Purchased numbers remain reserved
Verified
  • Successful approval
  • Reserved numbers automatically activated
  • You can purchase additional numbers: if they are in a new province, we only ask for that province’s invoice
Rejected
  • Signed document or province invoice not approved
  • The payment for the numbers that depended on this verification is canceled (you are not charged)
  • Those reserved numbers are released
  • You can try to verify again with corrected PDF documents

​
Number Lifecycle

Phone numbers go through different states during their lifetime in your project.

​
Number States

The number is temporarily assigned to your project during the purchase or verification process.
  • Not yet active for calls
  • Remains in this state during verification
  • Automatically activated upon verification approval
The number is fully active and operational.
  • You can assign agents for inbound and outbound calls
  • Billed monthly (€1.95/month + VAT)
  • Appears in your list of active numbers
You have released the number, but it is in a 30-day quarantine period.
  • You cannot use it for calls
  • Other customers cannot purchase it during this period
  • Still visible in your panel (marked as “In quarantine”)
  • Agents are automatically unassigned
After quarantine, the number becomes available for purchase again.

​
Quarantine Period

When you release a number, it enters a 30-day quarantine period before being available to other customers. Why does quarantine exist?
  • Prevents recently released numbers from being immediately purchased by other companies
  • Allows time for contacts to update their records
  • Reduces confusion for customers who may have the number saved
During quarantine, the number can no longer be used for calls and is not billed. You cannot reactivate a released number. If you need to recover it, contact support.

​
Number Billing

​
Monthly Cost

Each Diga phone number has a fixed cost:
  • €1.95 + VAT per number per month
  • Monthly billing independent of your subscription plan
  • Charged along with your monthly minutes invoice

​
Troubleshooting

​
I cannot purchase additional numbers

Cause: Your company has a pending verification. Solution:
  • Complete the identity verification process
  • Once approved, you can purchase additional numbers

​
My payment was authorized but the numbers are not active

Cause: You have a pending identity verification. Explanation:
  • Payment is authorized but not captured
  • Numbers are reserved awaiting verification
  • They will be automatically activated upon verification approval

​
My verification was rejected

Solution:
  1. Review the reason for rejection in the email you received
  2. Re-sign the verification document with a valid company or self-employed (autónomo) digital certificate, and check that the province invoice is valid
  3. Retry the verification process
  4. The previous payment was canceled, you were not charged

​
I released a number by mistake

Released numbers cannot be recovered. They enter a 30-day quarantine and then become available to other customers.
If you released a number by mistake:
  • It is not possible to reactivate it
  • You can purchase a different number immediately
  • The released number will not be available to others until after 30 days
