Making your website multilingual using hreflang tags? While hreflang tags are a must-have for helping people view the appropriate language and regional versions of your web pages, be sure to use the right hreflang language codes when adding hreflang tags to your website.
There are many hreflang language codes available, and they might not be as intuitive to guess as you might think. As an example, the hreflang language code for the Simplified Chinese language isn’t “ch”, but “zh”. Using the wrong language codes can mean sending visitors to the wrong language version of your web pages and creating a poor user experience as a whole.
With this in mind, let’s take a look at what hreflang language codes are and how you can easily implement them on your website. We’ll also share a list of hreflang language codes for convenient reference.
What are Hreflang Language Codes?
Hreflang language codes are two-letter language codes used in hreflang tags to indicate the language that a web page is in. As you may already know, hreflang tags are HTML code snippets that signal to search engines the language and geographical region for which a particular web page was created. If you need a refresher on hreflang tags, we’ve got a comprehensive guide to hreflang tags here.
Each language has a specific language code – for example, the hreflang language code for Spanish is “es”, while the German language has the “de” language code. (We’ll provide a fuller list of language codes shortly.) To help search engines accurately identify the language of your web content, you’ll need to use the correct language code in your hreflang tags. You can’t simply use random two-letter combinations that suit your fancy!
While you can use hreflang language codes on their own, it’s best to use them together with the ISO 3166-1 alpha-2 hreflang regional codes. This helps give search engines a full picture of which language and geographical region a particular web page is meant for. That’s because people in different countries may seemingly speak the same language, but with regional variants in spelling or slang.
As an example, “en” is the language code for English. Just from looking at this language code, though, you wouldn’t know whether it’s referring to American English or British English. And there are differences between the two, such as how Brits spell the word “colour” with a “u”, while Americans spell the same word as “color.”
Hence, for more accurate language and geographical signposting, pair the “en” language code with the “US” and “GB” regional codes for the United States and the United Kingdom respectively. By doing so, you clarify to search engines which web page is meant for English language searchers from the United States, and which one is meant for English language searchers from the United Kingdom. This in turn ensures effective international SEO (search engine optimization) for your website.
What are the Hreflang Language Codes Used for Different Countries?
The hreflang language codes are based on the ISO 639-1 list of language codes set by the International Organization for Standardization. Here are some of them:
How to Implement Hreflang Tags (And Their Language Codes)
Before you can reap the benefits of hreflang tags, you’ll need to add them to your website. We’ll go through two main ways, including how you can specify the appropriate language codes in your hreflang tags:
1. Manual Hreflang Implementation
To manually implement hreflang tags on your website, go to the head section of a web page that you want to add hreflang tags to. Then, compose your hreflang tag there, including the language code and (if relevant) regional code. Don’t forget that your hreflang tag attributes on a web page will also need to point to not just that web page, but also to its alternate language and regional variants.
As an example, you might have a global web page in English with the “https://www.example.com” URL. You also have an English version of the page for people from the United States, and a Portuguese version for people from Brazil. Accordingly, you should add the following hreflang tags to your global web page:
Repeat the above process for all the remaining web pages on your website.

The Manual Method of Implementing Hreflang Tags Isn’t Recommended
As you might be able to tell, manually implementing hreflang tags can take up a lot of time. This is especially if you have many web pages and need to create many hreflang tags. Even if you’re a web developer, you can expect to spend quite a bit of time adding hreflang tags to all the web pages on your website.
Apart from that, we don’t recommend manual hreflang implementation because:
It can slow your pages down: The more lines of code you add to your web pages, the longer your pages will take to load. This can affect your rankings on the search engine results pages (SERPs), as search engines generally prefer to rank pages with faster page load speeds. In addition, if your web page is taking too long to load, impatient visitors may just “bounce” and leave without browsing any further pages on your website. Not only does your bounce rate go up, which can hurt your SEO efforts, but you may also lose customers.
It leaves a lot of room for mistakes: Prepare too many hreflang tags and they can all start to blur together, causing you to make common mistakes. For instance, you may use the wrong language codes or country codes, or format your hreflang tags incorrectly. Search engines may then end up serving the wrong language content to the wrong searchers. If you see a “Your site has no hreflang tags” message in Google Search Console, this is a sign that there’s an error with your hreflang implementation that needs fixing.

Hreflang Language Codes FAQs
Are Hreflang Language Codes Case-Sensitive?
No, they’re not. However, the ISO recommendation is to display the language codes in lowercase, and the regional codes in uppercase.
Hreflang X-Default: What Is It and Can It Replace Language Codes?
The “x-default” hreflang attribute indicates that a web page doesn’t cater to any particular language or geographical region. Use this attribute, instead of hreflang language codes, in web pages to which search engines should be directing users if the search engine can’t find a more appropriate web page variant.
Can You Use Custom Hreflang Language Codes?
If you’re using Weglot to add hreflang language codes to your website, you can easily change the default language codes to something else. To do so, you’ll need to insert certain code snippets into your website. We have more information on this here.
