Free Online Tools

These free online tools help you check contact details, find location and industry codes, and explore common financial calculations. Choose a category below or search by name to find the tool that fits your task. Each page explains the information you need to enter and how to read the result, so you can work through a check without specialist software. Phone and email validators can help you spot formatting problems and understand the details returned for a contact. Lookup tools make it easier to find area codes, postal codes, country calling codes, and business classifications. Financial calculators let you explore growth, cash flow, valuation, and investment assumptions using your own figures. Use the results as a starting point for your work, and confirm important details with the relevant provider or official source. A valid format does not guarantee that a person can be reached, and a financial estimate depends on the assumptions you enter.
