Choosing the right phone number depends on your business goals, customer base, and the specific rules in each country. For local presence, geographic numbers are ideal. Toll-free numbers increase accessibility and encourage customer contact, but eligibility and usage rules can vary by country. International numbers help you establish a local presence abroad, while premium-rate numbers can generate revenue. The right choice depends on your industry, target audience, and operational strategy, with local telecom regulations playing a key role in the decision.
