On Searching anything on google chrome regarding my sitecore website then it showed 5 digit language code in search page breadcrums in the US region, not able to replicate in indian region can it be resolved anyhow? we only want two digit url
Search Engine crawls website urls through Sitemap. You can check if you have embedded language in US region site. If yes, you need to get rid of that. Once you update it, you can notify google about change in sitemap manually through this url,
You can find how it works for other search engines, else you will have to be patient since search engines have already crawled urls of your site. It will update gradually.
And, at last, you can get rid of language code from urls by setting 'languageEmbedding' to'Never' in LinkManager.
