TEFL Certification is training, which helps teachers teach English to students in a country where English is not the native language. TEFL certification is recognized for teaching in non-native English language speaking countries. TEFL is the accepted certification for teaching English by the institutions. TEFL offers specific training as the focus remains on teaching non-native English speakers. TESOL is the certification that trains teachers to teach English in both non-English speaking countries and English-speaking countries. This training will help to get a job abroad and in your home country. TESOL is the new term, and it's less likely to be accepted in comparison to TEFL certification. TESOL courses are split between teaching to ESL and EFL language learners, and the learning is not specified for one purpose.  However, both the certifications refer to teaching English and are recognized by companies for getting the job. Both certificates offer complete training.
