PostalCodes.info 5 features
SerpApi 5 features
  • Global Coverage
    PostalCodes.info provides postal code data for a wide range of countries worldwide, making it useful for international applications that need to validate or look up postal codes across multiple regions.
  • Simple REST API
    The API follows a straightforward RESTful design, making it easy for developers to integrate into their applications without a steep learning curve or complex authentication flows.
  • Geolocation Data
    The service provides geographic coordinates (latitude and longitude) associated with postal codes, which is useful for mapping, distance calculations, and location-based features.
  • Lightweight Responses
    The API returns concise, structured data that is easy to parse and doesn't require heavy bandwidth, making it suitable for applications where performance matters.
  • Useful for Address Validation

Possible disadvantages

  • Limited Documentation
    The API documentation can be sparse and lacks comprehensive examples, detailed error code explanations, and thorough guides, making it harder for developers to troubleshoot issues or understand all available features.
  • Data Accuracy Concerns
    Some postal code databases may contain outdated or incomplete data for certain countries, as postal codes change over time and keeping a global database fully up-to-date is challenging.
  • Rate Limiting and Usage Restrictions
    The API may impose rate limits or usage caps that could be restrictive for high-traffic applications, potentially requiring paid plans to accommodate larger volumes of requests.
  • Limited Additional Features
    Compared to more established geocoding and postal code services (like Google Maps API or SmartyStreets), PostalCodes.info may lack advanced features such as address parsing, fuzzy matching, or detailed administrative boundary data.
  • Uncertain Reliability and Support
    As a smaller, less well-known service, there may be concerns about long-term availability, uptime guarantees, and the quality of customer support compared to major established providers.

What's the story behind your product?

SerpApi's answer:

Back in 2017, Julien Khaleghy, the founder of SerpApi, built an iOS app that can analyze data from a picture. iOS didn't have a proper machine learning framework back then. It was challenging: iPhones' RAM were limited, no GPU or no dedicated chip acceleration were available, using only CPU was painfully slow, and compiling/porting C code from machine learning framework like Tensorflow or Caffe to iOS wasn't straightforward. Oddly, all of this wasn't the most difficult part of this project. Collecting images from Google Images was.

In these projects, 80% of his time ended up being spent on scraping and parsing Google Images. And maybe only 20% on actual machine learning model training, UI design of the actual apps, and iOS programming. This is how SerpApi was born.

Who are some of the biggest customers of your product?

SerpApi's answer:

  • Airbnb
  • Nvidia
  • Meta
  • Shopify
  • Grubhub
  • and more!
