Before you can use numbers with Zendesk, you may be required to provide regulatory information and documentation. This is applicable to all numbers, irrespective of whether you are directly purchasing new numbers from Zendesk or planning to port existing numbers to Zendesk.
The need for a business verification arises from specific regulations in certain countries. These rules mandate businesses to verify their identity by associating an approved regulatory bundle with a number, and in some instances, registering your business information and use case.
This guide will walk you through the process of gathering and submitting the necessary regulatory information and documents to ensure compliance with the latest regulatory requirements, including restrictions and porting documents.
Identifying Regulatory Requirements
Start by selecting a country to review the specific regulatory data required. Depending on the country, you may also find details about porting and any restrictions set by the country's regulator.
Please be aware of these important points as you gather the documentation.
- All submitted documents (e.g., the business registration document) must be dated within the past 3 months. Submissions with documents older than this will be declined.
- For countries needing an 'Executed Letter of Authorization', click here, make a copy, and fill it out with your details.
- Where an authorized representative is required, an authorized representative is someone the business designates to act on its behalf, often listed on official documents or provided with a notarized power of attorney as proof of authority.
- PO Box is not acceptable where a local address is required.
Submitting a Business Verification
After reviewing the necessary information and assembling the required documentation, you have two options for submission:
- Self-Service Submission: You can choose to self-serve and submit your business verification by following the instructions provided on the Verifying your business for Zendesk phone number purchasing page.
- Assisted Submission: If you require assistance, you can reach out to Zendesk Customer Support. They will guide you through the process of submitting your business verification, provided you have the necessary information based on the list of countries.
Review Process
The review process can take up to 3 business days. It's crucial to factor in this timeline when planning to add a new number to your account. If you sent a self-service submission, you will be able to review the status in the Business Verification tab. If you contacted Zendesk Customer Support, they will keep you updated on your submission status.
The timeline for messaging submissions will be detailed separately in each section.
Post-Approval Process
Once your business verification (regulatory bundle) is approved, you can proceed with adding a new line or starting the port-in process.
Remember that certain number types can only be added by contacting Zendesk Customer Support as pointed in the Zendesk number availability and pricing page.

Brazil: Documentation Guidelines
In Brazil, when a company is registered, the relevant document issued is the "Cadastro Nacional de Pessoas Jurídicas (CNPJ)" certificate, provided by the Brazilian National Registry of Legal Entities. This certificate serves as the business registration document, confirming the company's legal existence and registration status. It can be downloaded from the official website.
Anatel, the Brazilian telecommunications regulator, limits the number of toll-free numbers to five per CNPJ. Exceeding this risks service interruption. To keep more than five toll-free numbers, submit separate verification bundles with unique CNPJs.
For example, to keep 25 toll-free numbers, submit five bundles, each with a unique CNPJ mapped to five toll-free numbers.

Important Update: New Chilean Regulations for Outbound Calls Starting Mid-August 2025
Starting mid-August 2025, new local regulations in Chile require using specific phone number prefixes for outbound calls, depending on the call type:
- 600 numbers: For commercial communications when the customer has explicitly requested the contact.
- 809 numbers: For unsolicited or mass outreach campaigns.
Exemptions: Emergency alerts, two-factor authentication messages, and certain government surveys are not affected by this change.
Please note that Chilean telecom operators will monitor compliance and may block calls that do not follow these requirements. Calls reported by end users risk escalation and blocking by the carrier.
To avoid disruption, ensure you are using the correct number prefixes based on your call purpose.

It can take up to three business days to register the URL. However, you can submit multiple URLs for registration in the same support ticket. To send outbound SMS to numbers in Taiwan
Note: From October 8, 2025, outbound SMS to Taiwanese numbers (+886) that do not begin with a registered brand name may be blocked or flagged by Taiwan operators due to updated NCC requirements; broader enforcement is expected November 1, 2025. To avoid your SMS being blocked, you must register your SMS brand and ensure all messages to Taiwan begin with that brand at the very start of the message body. Every SMS to Taiwan must begin with the exact brand you submitted, at the very start of the message. Here are some examples of what this change to SMS content looks like in practice:
