BUILT AROUND CALL-CENTER PLANNING

Tailored to how you work.

In-house calling teams

Explore our country libraries and compare field structures for your internal telemarketing plans. Define the market, audience, and information your agents need before choosing a package.

Outsourced call centers

Discuss the calling-list requirements of your client campaigns with us. Keep each client’s data specification, access permissions, and suppression process clearly documented.

Telemarketing agencies

Compare country options and plan data requirements around your campaign brief. Package suitability depends on coverage, available fields, freshness information, and the intended calling method.

KNOW WHAT YOU ARE IMPORTING

Understand the fields in each library.

We help you assess a phone number library as an input to your calling workflow. A large record count alone does not explain whether the data fits your market, platform, or campaign.

Start with the phone-number field, then confirm country codes, number types, and any supporting attributes. Ask us for the actual package specification rather than assuming every country library has identical fields.

FieldWhat to confirm with us
Phone numberAvailability, format, and whether the package contains mobile numbers, landlines, or a mixture.
Country codeWhether supplied separately or within the phone-number field.
LocationAvailable country, region, or city fields and how they were assigned.
Contact nameWhether included and the completeness of the field.
Source informationPackage-specific source categories and available supporting documentation.
Update informationWhether a date refers to collection, maintenance, or a defined validation check.

Field availability varies. A phone country code does not, by itself, establish current residence or the appropriate calling time.

A SIMPLE PLANNING PROCESS

Five steps to your calling list.

  1. Select your market. Choose the countries or regions relevant to your campaign.
  2. Confirm fields and file format. Compare the available specification with your platform’s import requirements.
  3. Review sample availability. Ask us about a sample for the library you are considering.
  4. Prepare suppression screening. Plan the checks needed for your campaign, including internal objections and relevant registries.
  5. Confirm order and delivery. Discuss record volume, current price, delivery timing, and applicable purchase terms.

A CALLING LIST IS ONLY THE STARTING POINT

Plan for better calling campaigns.

We organize this library directory around the questions call-center teams need to resolve before ordering. Our focus is on the country package, its available fields, and the information needed to assess its suitability.

Number formatting

Confirm how international prefixes, country codes, and leading zeros are represented. Preserve phone fields as text during import to avoid losing meaningful characters.

Duplicate handling

Ask us how duplicates are defined for your package. Normalize formats consistently, then check overlap against your existing CRM records and previous campaign files.

Freshness information

Request the available collection, update, or check date. Number ownership and service status can change, so a historical check should not be treated as a live connection guarantee.

What a Quality Percentage Should Explain

If an accuracy figure is discussed for a package, ask us which attribute it measures. The definition, test date, sample size, exclusions, and error categories matter. A formatting pass rate is different from a live connection rate or sales conversion rate.

Phone validation and permission to call are separate checks. Purchasing a library does not itself establish recipient permission or remove campaign-specific restrictions.

Prepare Your Calling Process

Before outreach, assess applicable do-not-call and internal suppression requirements, calling hours, caller identification, and the rules relevant to your calling method. Requirements can differ between manual, automated, and prerecorded calls.

For US campaign planning, consult the FTC’s Telemarketing Sales Rule guidance. Other destinations require their own review. We do not present our library as automatic approval for a campaign.

What is a phone number library for call centers?

Our phone number library organizes country-specific phone data options for teams planning telemarketing campaigns. Start with the market you want to call, then confirm the package fields, record volume, update information, and permitted use with us.

Which countries can I explore?

Use our country directory above to open the available library pages. A listed country page is a starting point; contact us to confirm current package availability and coverage before ordering.

Do your libraries include mobile or landline numbers?

Number types can vary by package. Ask us whether your chosen library contains mobile numbers, landlines, a mixture, or a documented line-type field. Do not assume every telephone number supports every channel.

What fields are included?

Phone numbers are the core field to confirm. Names, location attributes, source information, and update details may vary. Request the actual specification for the library you intend to purchase.

Can I request a sample?

Contact us about sample availability for your selected country library. Use the sample to inspect number formatting, field names, missing values, and suitability for your import workflow.

What delivery format will I receive?

Confirm the available file format with us before ordering. Tell us whether your workflow needs CSV, TXT, or another supported format, and discuss column structure and encoding requirements.

Will the data work with my dialer or CRM?

Compatibility depends on your platform and its import requirements. Compare our available file specification with your system documentation. We do not imply a direct integration or guaranteed compatibility with every platform.

How are duplicate numbers handled?

Ask us about the duplicate definition and handling applied to your chosen package. Normalize number formats before checking your own files, and assess overlap with previous purchases and existing CRM records.

When was the library last updated?

Contact us for the available collection, update, or check date for the selected package. A webpage publication date is separate from a phone record’s last check date.

Are the numbers screened against do-not-call lists?

Confirm which screening, if any, applies to your package, its date, and its jurisdiction. Your call-center process should separately address relevant national registries, internal suppression lists, objections, and campaign-specific restrictions.

Does buying a library give permission to call?

No. Purchasing our data does not itself establish permission for a telemarketing call. Assess the applicable rules for the destination, recipient, purpose, and calling method before loading a campaign.

How do I raise a quality issue or privacy concern?

Contact our team with the package name, order reference where applicable, and a description of the issue. For personal-data concerns, use our Privacy Policy and Do Not Sell My Info page. Review our Refund and Returns Policy for purchase-related terms.
