File
Use UTF-8 CSV or the supported text format shown in your workspace. One phone number per line, a single column.
Large phone lists, handled as focused tasks.
Prepare your single-column file, choose one product and one country, review the quote, then let processing continue in the background.
A clean file is a better starting point.
Numbers
Use E.164 with the correct country code and leading +. Keep phone numbers as text; avoid scientific notation.
Country
Keep each task within one supported country. Split international lists into separate country files.
Review
Check the upload validation, product, quantity and server quote before submitting. Keep your source spreadsheet locally.
Start with the example layout
Three fictional US numbers in one column, without a header. Replace them with data you are authorized to process.
+12025550101 +12025550102 +12025550103
How it works
Upload once. Let the task run.
- 01
Sign in
Create an account or sign in to manage your balance, batch tasks and generated result files in one private workspace.
- 02

- 05
Download results
When the task is complete, download the product-specific result file for list cleaning, segmentation, routing or your next outreach step.
When a file needs attention, know what to do.
Unsupported file
Export a supported single-column file and upload again.
Extra columns
Create a separate file containing only E.164 phone numbers.
Wrong country or format
Correct country codes and split mixed-country lists.
Insufficient balance
Review the exact quote and add sufficient balance before confirming.
Understand your results
Field definitions, missing signals and what each product does not establish.
Choose the signal your next list needs.
Sign in, upload your phone list, review the server quote and track processing in the background.
