What is a 'lookup' in US Autocomplete's pricing?

A 'lookup' generally refers to a single API request made to US Autocomplete's services, whether it's for address autocomplete suggestions, validating a complete address, or performing a geocoding query. All these operations count towards your monthly lookup allowance.

Does the free tier have feature limitations?

No, the free tier typically provides full access to all API features, including US and International address autocomplete, validation, and geocoding. The only limitation is the monthly lookup volume of 500.

What happens if I exceed my plan's included lookups?

If you exceed the lookups included in your Starter, Growth, or Professional plan, you will be charged an additional per-lookup fee for the excess volume. This rate is typically lower than the base per-lookup cost within the plan and varies by tier.

Are International Address services included in the same pricing plans?

Yes, US Autocomplete's pricing plans typically include both US and International Address Autocomplete and Validation API calls within the same lookup count, simplifying billing and usage tracking across different geographical needs.

Can I upgrade or downgrade my plan?

Yes, US Autocomplete usually allows users to upgrade or downgrade their plans based on changing usage needs. This is typically managed through the user's account dashboard, with changes often taking effect in the next billing cycle.

Does US Autocomplete offer an Enterprise plan?

Yes, for very high-volume users or those with specific custom requirements, US Autocomplete offers an Enterprise plan. This plan typically involves custom pricing, negotiated lookup volumes, and potentially dedicated support or specialized features.

How can I monitor my lookup usage?

US Autocomplete provides a user dashboard where you can track your real-time lookup consumption for the current billing cycle. This helps you manage costs and determine if you need to adjust your plan.

US Autocomplete Pricing: Tiers, Free Plan & Examples (2026)

Pricing overview

US Autocomplete offers a usage-based pricing model designed to accommodate varying levels of address validation and autocomplete needs. The cost structure is primarily determined by the number of "lookups" performed per billing cycle. A "lookup" typically refers to a single API request for address autocomplete, validation, or geocoding services. This model aims to provide scalability, allowing users to pay only for the resources consumed rather than a fixed subscription independent of actual usage. The service includes a free tier for initial exploration and development, followed by tiered paid plans starting at a base monthly fee for a set number of lookups, with incremental costs for exceeding those limits. The pricing structure is detailed on the official US Autocomplete pricing page.

The API services covered under this pricing model include the US Address Autocomplete API, US Address Validation API, US Geocoding API, International Address Autocomplete API, and International Address Validation API. This consolidated approach means that various address-related operations contribute to the same lookup count, simplifying cost estimation for users integrating multiple services. The platform also emphasizes compliance with data privacy regulations such as GDPR requirements for data processing, which can be a factor for businesses operating within or serving European markets.

Plans and tiers

US Autocomplete provides several distinct plans, each tailored to different usage volumes and offering specific lookup allowances. All plans are billed monthly. The pricing structure is designed to offer better per-lookup rates as usage scales up, incentivizing higher volume commitments. Each plan includes access to the full suite of US Autocomplete APIs, including both US and International address services.

Plan Comparison Table

Plan Name	Monthly Price	Monthly Lookups Included	Cost Per Additional Lookup	Best For
Free Tier	$0	500	N/A (upgrade required)	Development, testing, very low-volume personal use
Starter	$15	5,000	$0.003	Small businesses, startups, moderate e-commerce sites
Growth	$49	20,000	$0.0025	Growing businesses, CRM integration, medium-volume logistics
Professional	$149	75,000	$0.002	Large e-commerce, enterprise-level lead generation, high-volume data cleansing
Enterprise	Custom	Custom	Custom	Very high-volume operations, specific compliance needs, dedicated support

The transition between tiers is automatic for increasing usage, and users typically have dashboards to monitor their current lookup consumption. For the Starter, Growth, and Professional plans, exceeding the included lookup volume results in an additional charge per lookup, as specified in the table above. Enterprise plans are typically negotiated directly with US Autocomplete to address specific requirements for very large-scale operations or unique use cases that may require custom features or dedicated support, as outlined in their detailed pricing information.

Free tier and limits

US Autocomplete offers a free tier that includes 500 lookups per month. This free allocation is designed to allow developers and businesses to test the API's functionality, integrate it into their applications, and conduct initial evaluations without any financial commitment. The free tier provides full access to the API features, meaning users can experiment with US address autocomplete, validation, geocoding, and international services just as they would with a paid plan.

The primary limit of the free tier is the lookup volume. Once 500 lookups are consumed within a calendar month, API requests will typically cease to function or return an error indicating the limit has been reached. To continue using the service beyond this limit, users must upgrade to a paid plan. There are generally no feature restrictions on the free tier beyond the usage volume, making it a suitable environment for proof-of-concept projects and low-volume applications. Details on how to sign up for the free tier and monitor usage are available within the US Autocomplete documentation portal.

Real-world cost examples

To illustrate the practical application of US Autocomplete's pricing model, consider the following scenarios:

Small E-commerce Store (5,000 lookups/month): A small online retailer uses US Autocomplete for its checkout forms, processing approximately 5,000 address lookups monthly. This volume aligns with the Starter plan. The monthly cost would be $15.
Mid-sized Logistics Company (35,000 lookups/month): A logistics company integrates the API for route optimization and delivery address validation. If they perform 35,000 lookups monthly, this exceeds the Growth plan's 20,000 included lookups.

Base cost (Growth plan): $49
Additional lookups: 35,000 - 20,000 = 15,000
Cost for additional lookups: 15,000 * $0.0025 = $37.50
Total monthly cost: $49 + $37.50 = $86.50

Large CRM Platform (100,000 lookups/month): A CRM provider uses US Autocomplete for data cleansing and lead enrichment across its user base, generating 100,000 lookups per month. This exceeds the Professional plan's 75,000 included lookups.

Base cost (Professional plan): $149
Additional lookups: 100,000 - 75,000 = 25,000
Cost for additional lookups: 25,000 * $0.002 = $50
Total monthly cost: $149 + $50 = $199

High-Volume Enterprise (500,000+ lookups/month): A large enterprise with extensive global operations requires address validation for millions of customer records annually. At this scale, they would typically engage with US Autocomplete for a custom Enterprise plan. The exact pricing would be negotiated based on projected volume, specific service level agreements (SLAs), and any custom integration or support needs.

These examples illustrate how costs scale with usage, with the per-lookup price decreasing in higher tiers and for additional lookups within those tiers. Users can monitor their usage through a provided dashboard to optimize their plan selection and manage costs effectively, as highlighted in the US Autocomplete REST API documentation.

How the pricing compares

When evaluating US Autocomplete's pricing, it is useful to compare it against alternative address validation and autocomplete providers in the market. Key competitors include Smarty (formerly SmartyStreets), Loqate, and Melissa. While all these providers offer similar core services, their pricing models, free tier allowances, and per-lookup costs can vary significantly.

Smarty (formerly SmartyStreets)

Pricing Model: Smarty typically offers tiered plans based on "lookups" or "requests," similar to US Autocomplete. They have separate pricing for US Street Address Validation, US Autocomplete, and International services. Their pricing can sometimes be broken down further by specific API endpoints, which might lead to different cost structures depending on the exact services consumed.
Free Tier: Smarty also provides a limited free trial or free tier, often with a specific number of lookups for testing purposes, such as Smarty's free trial for US address validation.
Cost Comparison: For similar lookup volumes, Smarty's pricing can be competitive, though direct comparisons require careful mapping of specific features and API calls to ensure an apples-to-apples evaluation. Some users report that Smarty's international pricing might be structured differently or offer different regional coverage options.

Loqate

Pricing Model: Loqate often employs a credit-based system where users purchase credits that are then consumed by various API calls (e.g., address validation, geocoding, autocomplete). Different API calls may consume different numbers of credits, making direct per-lookup comparisons more complex without understanding the credit conversion rates.
Free Tier: Loqate generally offers a free trial or a limited number of credits upon signup for evaluation purposes, as detailed on their Loqate pricing page.
Cost Comparison: Loqate's credit system can offer flexibility, but it requires users to understand the credit consumption of each API endpoint. For high-volume usage, the per-credit cost tends to decrease, similar to US Autocomplete's tiered per-lookup rates.

Melissa

Pricing Model: Melissa offers a range of data quality services, and its pricing can be more modular, available as subscriptions for specific services or through a credit system. They often provide bundled solutions for address, name, email, and phone validation.
Free Tier: Melissa typically provides a free trial or a developer account with a set number of credits or lookups for testing, as seen on their Melissa developer free trial.
Cost Comparison: Melissa's strength often lies in its comprehensive suite of data quality tools. While its address validation might be priced competitively, the overall cost could be higher if users are also leveraging other data enrichment and cleansing services from them.

In summary, US Autocomplete's straightforward usage-based model, with clear per-lookup costs and distinct tiers, offers transparency. While alternatives like Smarty, Loqate, and Melissa provide robust services, their pricing structures can be more complex (e.g., different pricing for specific services, credit systems) requiring detailed analysis based on specific use cases and anticipated lookup volumes to determine the most cost-effective solution.
